Audio Amplifiers for Portable Devices

Smart Amplifiers

Today’s audio technologies need to support portable equipment and audio component designs. Our audio amplifiers lead the industry for sound, robustness, and EMC performance. We invented the world’s first Smart Amplifier and ship more than 400 million low-power audio products per year.

Class D – Non-Boosted

Class D is crucial to save battery life and meet the output power requirements with low dissipation. Our Class D audio amplifiers provide protected mono solutions from 2.35 to 3 W, delivering audiophile sound quality while maximizing audio system capabilities.

Class D – Boosted

As speaker boost voltage requires precise speaker’s membrane excursion and coil temperature control based on the speaker’s characteristics, related firmware tuning is necessary. This firmware adaptation is either managed in external host processor for Programmable smart amplifiers or in Smart audio amplifiers embedding a Digital Signal Processor.

Our Smart audio amplifiers offer the most advanced solution to this conflict. They offer a turn-key solution for getting the most from micro-speakers.

End-User Benefits
  • Louder sound: The maximum possible volume from small speakers
  • Deeper bass: Reproduces lower audio frequencies than traditional systems
  • Better quality: Unmatched sound clarity with amplifier clipping and speaker distortion reduction
  • Longer life: Prevents speaker damage with adaptive excursion control and real-time temperature protection
